I can't see anything good coming of adding more items for purchase with old tiers of emblems. I'm sure everyone remembers farming kara for badges to buy items with equal budget to that of t6 gear, which is what blizzard explicitly wanted to prevent when they implemented tiered emblems. For people worried that they'll end up sitting on a stockpile of worthless emblems, there are plenty of things to buy with them already that can be sold on the AH at a profit. For Heroism, there are blue gems and frozen orbs, not to mention heirloom gear for alts, and for valor, there is a pair of BoE bracers for every spec in the game, the most desirable of which commands a cool 5k on the ah presently.
